Override Request_Client instead of Request so that we can get hold of the controller.
Use protocol flat in Url::site()
Display versions on test result page
don't add protocol to url::site call after all
Override Request_Client_Internal instead of Request_Client to work with Kohana 3.1 as well
Add version info to README
Allow overriding Request_Client_Internal
Issue #5: Make module work with Kohana 3.3 (as well as 3.2 and 3.1)
